Random Installation of English-United States-US Keyboard

[jmt356]

About once per day, Windows randomly seems to install the English-United States-US keyboard. It usually happens while I am trying to switch between my Arabic and English-United States-International keyboards by pressing the alt + shift shortcut, so I suspect the issue can be that I am accidentally pressing something on the keyboard that causes the English-United States-US keyboard to be installed.

What am I pressing and how do I stop this from happening?

I want to configure Windows so that the only English keyboard I have is English-United States-International. I do not want the English-United States-US keyboard to ever be installed.

There are endless discussions about this problem on the Microsoft forums. There doesn't seem to be a simple solution that works for everybody.
You might try the last reply in windows keeps automatically adding EN-US keyboard layout.

I've never been able to resolve UK to US occurring every time I get Microsoft Updates needing restart.
